Fin stabilizer with adjustable arc

Abstract

The invention discloses a fin stabilizer with an adjustable arc. The fin stabilizer comprises a fin frame; the periphery of fin frame is provided with an upper and a low fin surface oppositely arranged and an end cap used for closing both end portions of the two fin surfaces; each fin surface is made by the sequential lapping of a plurality of reversible fin arc plates; the first and the last fin arc plate are hinged on the fin frame; a transmission system used for driving each fin arc plate to flip is arranged on the fin frame. With the fin surfaces made by the sequential lapping of a plurality of the reversible fin arc plates, control on stabilizing lift is greatly facilitated. According to the stabilizing torque needed, the transmission system is capable of adjusting the shape of the fin surfaces organically, obtaining the right stabilizing torque, generating corresponding stabilizing lift, passing the stabilizing lift to a hull at the same time and thus forming an effective stabilizing moment on the hull under different speed and different level of wind and waves. Consequently, the fin stabilizer with the adjustable arc is capable of effectively stabilizing in any complex waters and greatly improving stabilizing efficiency.

Description

technical field [0001] The invention relates to a fin stabilizer, in particular to a fin stabilizer with an adjustable arc surface. Background technique [0002] When the ship is sailing at sea, the wind, waves and other uncertain weather have a great impact on the dynamic stability of the ship. Often due to the severe shaking of the ship, the cargo is damaged, the crew's work efficiency is reduced, and even the maritime combat mission is affected, such as: Combat system fire control stability, anti-submarine helicopter takeoff and landing, etc. during combat. The damping of the ship's rolling motion is very small, so the ship will roll violently in the wind and waves. In order to reduce ship rolling, people have designed various anti-rolling devices, but there are not many practical applications. The reason why anti-rolling devices are largely eliminated is that the requirements for use are high, but anti-rolling devices should be effective, reliable, and economical. So ...

AI Technical Summary

Problems solved by technology

[0005] The fin stabilizer adjusts the shape of the fin surface through the expansion and contraction of the connecting rod, but the expansion and contraction range of the connecting rod is constant, and the resulting anti-rolling lift is also constant, so that the ship can sail at different speeds and under different wind and wave levels When , the anti-rolling efficiency is poor and the anti-rolling reliability is low
